لطفاً این متن رو اگه زحمتی نیست ترجمه کنید.
the tempreture coefficient of constantan can be held within +_20 ppm/c of ambient tempreture . however, the difference in TCR between the low and high tempreture ranges is about 20 ppm. Thus, the specification is about +_ 20 ppm/c over one tempreture range or +_ 40 ppm/c over both ranges.
اون مثبت و منفی ها رو نتونستم زیر هم بذارم !)
suitable soldered or silver-brazed connections can be made readily using appropriate fluxes.
منظور از flux چیه این جا ؟!
this alloy is used primarily to accoplish specific design objectives because it permit designers to vary wire diamater and wire coating in order to accomodate design constraints. such as serve space limitations.
و این یکی :
these alloys are not made to rigid specifications that apply to manganins. For these alloys stability is not critical.
